Preschool Science Lesson Plans - Shiny Pennies

One of the traditions during the Chinese New Year celebration is to give children red envelopes containing brand new money.

Try making pennies shine like new again with this classroom activity. Make this into a real science experiment by trying 4 different ways to shine the pennies and see which one works best. Ask the children what they think will happen. Encourage them to observe and describe what happens after dipping each penny into one of the bowls.


1 bowl vinegar

1 bowl salt

1 bowl salt and vinegar

1 bowl salt and water

Fill 4 bowls with the ingredients listed above and see what happens when you dip in a penny.

Combine 1/2 cup vinegar with 4 tablespoons salt in the third bowl.

It is such fun to see the reactions of the kids as they watch the shine come back to their "lucky" penny! Let them take their lucky pennies home as their Chinese New Year's gift.
